Abstract
The utility model discloses a back-to-back 35kV indoor-type SVG dynamic reactive power compensation device. The device comprises a machine cabinet and power modules which are positioned inside the machine cabinet. The axis of the machine cabinet is provided with an air bin in a vertical way. The power modules are symmetrically positioned around the air bin in a four-row structure. An inlet wire copper bar is connected with the power module of the lowest end of any row of the power modules. Power modules of each row are connected in series via a connecting copper bar. Two adjacent power modules are connected via a bridging copper bar positioned in a horizontal way. The power modules in the machine cabinet form a series structure, and an outlet wire copper bar is connected with the last power module in the series structure. Any one of the two among the power modules connected in series and the shell of the machine cabinet are connected with a clamp via a conductive wire. The number of the power modules is 12 or an integer multiple of 12. Therefore, a most compact structure under a condition that the number of the power modules in a high voltage SVG device is relatively high can be realized so that an occupying area of the device can be reduced.

Background technology
Static reacance generator is called for short SVG, is present state-of-the-art reactive power compensation technology in the world.The basic principle of SVG is with voltage source inverter, process reactor or transformers connected in parallel are on electrical network, by regulating amplitude and the phase place of inverter AC output voltage, absorb rapidly or send needed reactive power, realize the purpose that quick dynamic adjustments is idle.The 35kV reactive power compensator need not boost, and only linked reactor can in parallelly with electric power network compensate.But the chain type dynamic reactive compensation device is realized phase voltage by the units in series of some.Traditional approach adopts three layers of arrangement mode of three-phase separate, layer insulation and unit insulation against ground are difficult to process, and when 35kV indoor type SVG device of the prior art adopted the air cooling mode, density of heat flow rate restriction and 35kv electric clearance and creepage distance double factor had determined that its floor space is usually larger.
The utility model content
For the defective that exists in the prior art, the purpose of this utility model provides a kind of back-to-back formula 35kV indoor type SVG dynamic reactive compensation device.
For achieving the above object, the utility model adopts following technical scheme:
A kind of back-to-back formula 35kV indoor type SVG dynamic reactive compensation device, the arrangement that comprises rack and be located at the power model in the rack, vertically be provided with the wind storehouse on the axis of described rack, described power model with 4 row symmetrical configuration be located at the wind storehouse around, bottom a power model links to each other in inlet wire copper bar and the arbitrary row power model, by connecting the copper bar serial connection, link to each other by horizontally disposed cross-over connection copper bar between the adjacent two row power models between the power model in every row; Power model in the described rack forms the structure of a series connection, and outlet copper bar links to each other with last power model in the cascaded structure; In two of the centres of the power model of described series connection any one and rack enclosure are by the mechanical connector position;
The quantity that described scheme is applicable to power model is the chain type reactive power compensator of 12 or 12 s' integral multiple.
Described inlet wire copper bar and outlet copper bar are drawn by wall bushing in described wind storehouse.
Described connection copper bar and cross-over connection copper bar are located at respectively the outside of power model.
Also comprise centrifugal blower, described centrifugal blower adopts the 35kV insulator to make somebody a mere figurehead above rack, and centrifugal blower is tightly connected by the bellows of insulation material and the upper end in described wind storehouse.
Compared with prior art, adopt a kind of back-to-back formula 35kV indoor type SVG dynamic reactive compensation device of the present utility model, can realize in the high pressure SVG device the cramped construction in the more situation of power model number, thereby reduce occupation area of equipment.
